Kernel Security Checker is a useful tool to locate
attackers residing within a system by employing a
direct analysis of the kernel through /dev/kmem and
bypassing the hiding techniques of the intruder (kernel
static recompilation or use of LKMs). It can find the
modified syscalls from userspace, detect the
promiscuous interfaces, and find the modifications
applied to a protocol.

net-status-monitor is a simple console script to
test whether Internet connectivity is working. If
it is, the script tells you the external IP
address (in case your dynamic DNS provider is
down). If not, it tries to find the point where
the connectivity fails. The output is quite
simple, so you can put it on your grandmother's
PC. "Just tell me what the read line says" should
give you enough information.

mempattern is a utility for generating bit patterns on address and data lines of memory buses in computer systems. This allows hardware engineers to observe and measure the electrical characteristics of the memory bus interface.
